Wikipedia Foundation Files Amicus Brief in AI Copyright Case
Current overview (not historical)
The Wikimedia Foundation has filed an amicus curiae brief in a landmark U.S. copyright case involving large‑language‑model training. The brief argues that courts should require the use of licensed content when training AI systems, but should not extend copyright protection to the chatbot’s output that users receive. The Foundation warns that overly simplistic rulings could either stifle innovative uses of copyrighted works or allow AI companies to ignore licensing agreements, thereby disrupting the flow of knowledge between creators and audiences. This filing follows a broader debate over how copyright law should apply to AI training and user-facing outputs, with the Foundation emphasizing the need for a balanced approach that protects both creators’ rights and the openness of the web.

- The Verge · AIRelated fact: single sourceSource report revisedWikimedia Urges Courts to Protect LLM Training on Copyrighted Works While Safeguarding Open Web
Report first recorded Oct 30, 18:48
The Wikimedia Foundation, operator of Wikipedia, filed an amicus brief in a series of high‑profile AI copyright lawsuits involving publishers such as The New York Times and AI firms OpenAI and Microsoft. The brief argues that courts should grant legal protection for large language models (LLMs) that are trained on copyrighted material, but should not extend that protection to chatbots that reproduce that material for users. Wikimedia warns that a blanket ruling in favor of publishers could allow copyright holders to "gatekeep" even transformative uses of their content, while a ruling favoring AI companies could "snub licensing terms" and fragment the flow of knowledge between authors and audiences. The foundation stresses that Wikipedia sites are a critical data source for AI training, yet the same AI systems can undermine Wikipedia’s sustainability by diverting traffic and violating Creative Commons licenses. Wikimedia’s general counsel, Stephen LaPorte, notes that careful application of fair‑use principles is essential to preserve free knowledge and open‑source technologies.
